Overview
The NLV74HCT4851ADRG is an automotive-grade analog switch and multiplexer manufactured by onsemi. It belongs to the MC74HCT4851A series, utilizing HCT CMOS technology for compatibility with TTL logic levels. The device integrates a single 8-to-1 multiplexer/demultiplexer circuit within a compact 16-SSOP surface-mount package. Designed for robust performance in demanding environments, it supports a wide operating temperature range from -55°C to +125°C. The component meets AEC-Q100 standards, ensuring reliability for automotive applications while maintaining low power consumption typical of high-speed CMOS devices.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for enhanced reliability
- High-speed HCT CMOS technology ensures compatibility with standard TTL logic inputs
- Wide operating temperature range suitable for harsh automotive environments
- Single-channel 8:1 multiplexing capability in a compact SSOP package
Applications
- Automotive data acquisition systems requiring signal routing
- In-vehicle communication networks for channel selection
- Industrial control modules operating under extreme temperatures
- Battery management systems for sensor signal multiplexing
Procurement Notes
Verify the specific suffix 'DRG' against the official onsemi datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure the procurement source provides valid AEC-Q100 certification documentation. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the RoHS status aligns with project requirements, as automotive parts may have specific environmental compliance declarations.
Selection Notes
Select this component when an automotive-grade 8:1 multiplexer is required for systems interfacing with TTL-level logic. The HCT series is appropriate for designs needing direct compatibility with 5V logic families without additional level shifting. Consider the 16-SSOP package dimensions for PCB layout constraints. Verify that the operating voltage range and leakage current specifications meet the system's power budget and signal integrity requirements.
Part Context
This part is a member of the MC74HCT4851A family, which includes variants like the MC74HC4851ADWR2 and NLV74HC4851AMNTWG. While the HC series offers lower power consumption, the HCT series provides better noise immunity and TTL compatibility. The NLV prefix specifically denotes automotive-grade quality, distinguishing it from standard commercial grade parts. This family shares functional similarities but differs in packaging, temperature ratings, and qualification standards.
Replacement Considerations
Direct replacements include other automotive-grade 8:1 multiplexers from the same family, such as the NLV74HC4851AMNTWG, though pinout and package differences must be verified. Commercial equivalents like the MC74HC4851ADWR2 lack automotive qualification and should only be considered if environmental ratings are relaxed. Always check datasheet electrical characteristics for compatibility before substitution.
